Of course they created their own god, as did all myth-makers create their own gods and goddesses through the eons of time concerning religion.
Some certain Jews thought they were special and so they needed one god all their own. Previously Jews were polytheistic and believed in multiple gods.
You really need to be more objective concerning religion and as long as you stay PUT in Catholicism, you will subject your self only to what suits your Catholic lusts.
My answer is in the form of a question:
If being a Christian is absolutely satisfying in all aspects, then why try to be objectively against it?
You are trying to make a false dilemma, but it seems more like a casual simplification....I am not quite sure. Good try.
So, if you only look objectively, the subjective is ignored. And vice versa. Ignoring the subjective is not being truthful or honest....
